Cochlear Function/ Otoacoustic Emmision

A small probe placed in the ear, wide frequency band quiet sounds are “played” into the ear.

A cochlea that is functioning normally responds to sound by sending a signal to the brain, while also producing an “acoustic emission” – a very small sound wave response sometimes called an echo that travels back through the ear.

The emission/echo is picked up by a tiny, sensitive microphone inside the probe and the response is measured and in about 30 seconds the result is summarized on the screen as a “pass” or a “refer.”

Diagnostic OAEs

The probe and placement are the same, but results are shown on a screen for the Audiologist to analyze.
